System limitations
WARNING
Unfavorable road condi-
tions and poor weather
conditions
The range of the radar sensor may be restricted by
rain, snow, ice, fog, stone chippings and spray. Ve-
hicles up ahead may not be adequately detected, or
may not be detected at all.
Reflective objects such as ice, heavy rain, crash bar-
riers or tunnel entrances may impair the functional-
ity of the radar sensor. A message indicating that the
driver assistance system is not available appears on
the instrument cluster.
e Do not use the driver assistance system under
such conditions.
WARNING
Undetected vehicles or
objects
The radar sensor detects a narrow, cone-shaped
area in front of your vehicle. As a result, vehicles or
objects may not be detected in time or cannot be
detected in the following situations:
– Vehicles driving erratically or weaving in and out
– Vehicles with a small cross-section or narrow
vehicles
– Vehicles entering and exiting curves
– Stationary vehicles
– Vehicles with large projecting loads
– Pedestrians, cyclists and animals
– Objects on the road
– Oncoming vehicles and cross-traffic
e Intervene and brake yourself if necessary.
e Drive with extreme care and always pay attention
to the traffic conditions and vehicle
surroundings.
Vehicles driving erratically or weaving in and
out and narrow vehicles
Fig. 7: Vehicles driving erratically or weaving in and out (A)
and narrow vehicles (B)
A vehicle that is driving erratically or weaving in and
out will only be detected if it is completely in its own
driving lane.
A narrow vehicle may not be detected in time, if at
all.
Vehicles entering and exiting bends and sta-
tionary vehicles
Fig. 8: Vehicles entering and exiting bends (C) and station-
ary vehicles (D)
Vehicles entering and exiting bends may not be de-
tected or may not be detected in time or the radar
sensor may react to vehicles in adjacent lanes.
A stationary vehicle or obstacle that suddenly ap-
pears in the radar sensor's range, e.g. after a vehicle
ahead changes lanes or at the end of a traffic jam,
may only be detected to a limited extent by adaptive
cruise control.
